Public Methods

Method	Description
Clone ( ) : object	Creates a new object that is a copy of the current instance.
CronExpression ( string cronExpression ) : System	Constructs a new CronExpressionString based on the specified parameter.
Equals ( CronExpression other ) : bool	Determines whether the specified CronExpression is equal to the current CronExpression.
Equals ( object obj ) : bool	Determines whether the specified T:System.Object is equal to the current T:System.Object.
GetExpressionSummary ( ) : string	Gets the expression summary.
GetFinalFireTime ( ) : DateTimeOffset?	NOT YET IMPLEMENTED: Returns the final time that the CronExpression will match.
GetHashCode ( ) : int	Serves as a hash function for a particular type.
GetNextInvalidTimeAfter ( DateTimeOffset date ) : DateTimeOffset?	Returns the next date/time after the given date/time which does not satisfy the expression.
GetNextValidTimeAfter ( DateTimeOffset date ) : DateTimeOffset?	Returns the next date/time after the given date/time which satisfies the cron expression.
GetTimeAfter ( DateTimeOffset afterTimeUtc ) : DateTimeOffset?	Gets the next fire time after the given time.
GetTimeBefore ( DateTimeOffset endTime ) : DateTimeOffset?	Gets the time before.
IsSatisfiedBy ( DateTimeOffset dateUtc ) : bool	Indicates whether the given date satisfies the cron expression. Note that milliseconds are ignored, so two Dates falling on different milliseconds of the same second will always have the same result here.
IsValidExpression ( string cronExpression ) : bool	Indicates whether the specified cron expression can be parsed into a valid cron expression
OnDeserialization ( object sender ) : void
ToString ( ) : string	Returns the string representation of the CronExpression
ValidateExpression ( string cronExpression ) : void
